Description

[Detailed description of the invention] Industrial application field This invention relates to a sheet guide for a rolled wet towel manufacturing device, and more specifically, to effectively prevent the sheet material fed by the feed roller from being rolled up by the roller. The present invention also relates to a sheet guide that can be easily assembled.

BACKGROUND OF THE INVENTION Coffee shops, restaurants, and other eating and drinking establishments provide "wrapped towels" as a customer service. Because this type of facility uses a large amount of rolled towels per day, most of them are currently supplied by towel manufacturers. However, while ``rolled wet towels'' made of towel cloth can be used repeatedly, they not only have the problem of being extremely unsanitary if the recycling process is incomplete, but also have the drawback of increasing costs.

Therefore, the applicant of this case has been working diligently to develop a compact rolling towel manufacturing device that can make inexpensive and disposable "wrapped towels" made of paper or non-woven fabric at home, and has filed multiple utility model registration applications. Summer. The rolled wet towel manufacturing apparatus according to these applications can fully automatically and efficiently manufacture a "wrapped wet towel" in which a sheet material made of paper or nonwoven fabric is wound into a roll. This idea is
In this rolled wet towel manufacturing apparatus, the sheet guide that is fed by the feed roller that constitutes the sheet material feeding mechanism is used to prevent the sheet material from being rolled up by the roller, so it will contribute to a basic understanding. First, we will explain the sheet material feeding mechanism and the conventional sheet guide in Section 5.
This will be explained with reference to the figures and FIG.

FIG. 5 is a longitudinal sectional view showing the main parts of the feeding mechanism and cutting mechanism of the rolled wet towel manufacturing device. feed roller 12
is rotatably disposed, and this roller 12 is configured to be rotationally driven in a counterclockwise direction via a drive mechanism (not shown). Further, the feed roller 12 includes a plurality of (four in the illustrated example) protruding outward in the radial direction.
Two O-rings 16 are wound at predetermined intervals in the axial direction, and these O-rings 16 function to smoothly pull out the sheet material 14 without causing it to slip on the rollers.

On the left side of the feed roller 12, there is a feed roller 1.
2 through the shaft 18 parallel to the "dog" shaped presser plate 2.
0 is rotatably supported. and presser plate 2
The upper bent piece 20a of 0 is always pressed against the O-ring 16 of the feed roller 12 under the elastic force of a torsion spring 22 disposed on the opposite side of the feed roller 12. Therefore, the feed roller 12 is rotated while the sheet material 14 pulled out from a sheet roll (not shown) stored on the right side of the feed roller 12 is inserted between the O-ring 16 and the presser plate 20. Then, the sheet material 14 sandwiched between the O-ring 16 and the presser plate 20 is sequentially pulled out as the roller 12 rotates.

As shown in FIG. 6, between the feed roller 12 and the presser plate 20 and below the pressure contact portion between the presser plate 20 and the O-ring 16, the roller 12 extends parallel to the feed roller 12 and A sheet guide 24 having an upwardly open notch 24a is disposed at a position corresponding to the disposed position of the O-ring 16 wound around the seat. As shown in FIG. 5, this sheet guide 24 has screws 26, 2 attached to both side plates 10a, 10a of the apparatus main body 10, with corresponding O-rings 16 protruding from each notch 24a toward the holding plate 20.
It is positioned and fixed via 6. Note that the upper end of the sheet guide 24 is positioned so as not to protrude outward beyond the outer peripheral surface of the O-ring 16.
Therefore, the leading end of the sheet material 14 being fed while being held between the O-ring 16 and the presser plate 20 is guided to a cutting mechanism (described later) below while making contact with the sheet guide 24, and is wound around the feed roller 12. Never.

Below the feed roller 12, on the right side of the sheet material 14 that is fed in a hanging manner from the roller 12,
As shown in FIG. 5, a fixed blade bracket 30 having a fixed blade 28 disposed thereon is arranged parallel to the width direction of the sheet material 14. As shown in FIG. Further, on the opposite side of the fixed blade bracket 30 and the sheet material 14, a rotary blade mounting roller 32 extending parallel to the fixed blade bracket 30 is rotatably supported.
A rotary blade 34 is disposed at 2. Therefore, the sheet material 14 passing between the fixed blade bracket 30 and the rotary blade mounting roller 32 is
By rotating the blade 2 in a predetermined direction, the blade is cut in the width direction under the cooperative action of the rotary blade 34 and the fixed blade 28.

Problems to be Solved by the Invention In the rolled wet towel manufacturing apparatus equipped with the feed roller 12 wrapped with the O-ring 16, the sheet material 14
In order to prevent the sheet material 14 from being caught up in the feed roller 12 and to achieve smooth feeding of the sheet material 14, the upper end of the sheet guide 24 must be positioned inside the outer peripheral surface of the O-ring 16 ( and the outer peripheral surface of the feed roller 12). That is, if the sheet guide 24
The upper end of the presser plate 2 is lower than the outer peripheral surface of the O-ring 16.
If the sheet material 14 protrudes toward the 0 side, the sheet material 14 that is fed while being in contact with the outer peripheral surface of the O-ring 16 will inevitably be caught on the upper end of the guide 24, making it impossible to feed the sheet material smoothly.

In this case, the work of adjusting the upper end of the sheet guide 24 to an appropriate position must be performed within a narrow space inside the apparatus, which is complicated. Further, since the sheet guide 24 is configured to be fixed to the device main body 10 via a screw 26, when adjusting the position of the sheet guide 24, the screw 26 must be loosened or tightened. This is a time-consuming task.

Here, when the sheet material 14 is cut by the cutting mechanism, a downward pulling force may be applied to the sheet material 14. In addition, the sheet guide 24
As shown in FIG. 6, the left and right ends are fixed to the side plates 10a, 10a with one screw 26, respectively. Therefore, if the sheet material 14 being cut comes into contact with the sheet guide 24, there is a risk that the guide 24 will rotate about the screw 26. At this time, if the upper end of the sheet guide 24 moves in a direction protruding outward from the outer peripheral surface of the O-ring 16, the sheet material 14 will get caught as described above and smooth feeding will no longer be possible, and the sheet guide 24 will move again. It becomes necessary to adjust the position of the

Purpose of the invention This invention was proposed in order to suitably solve the problems inherent in the rolled wet towel manufacturing apparatus equipped with the feed roller wrapped with the O-ring described above. To provide a sheet guide that prevents sheets from being caught up in a feed roller and that can be easily assembled without complicated position adjustment.

Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention involves wrapping a sheet material drawn from a supply source with a plurality of O-rings at predetermined intervals in the axial direction. The rolled wet towel manufacturing apparatus is configured to feed the wet towels through a feed roller, which includes a sheet guide rotatably supported and extending parallel to the feed roller, and the sheet guide includes a sheet guide that is rotatably supported and extends parallel to the feed roller. A first regulating piece and a second regulating piece are formed with a notch that allows the O-ring wound around the feed roller to pass therethrough, and expands at a required angle. By locating it close to the circumferential surface of the feed roller, when rotational force is applied to the sheet guide, one of the regulating pieces comes into contact with the circumferential surface of the feed roller and prevents rotation of the guide. It is characterized by being configured to obtain.

Embodiments Next, a preferred embodiment of the sheet guide of the rolled wet towel manufacturing apparatus according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a vertical cross-sectional view of a main part of a rolled wet towel manufacturing apparatus in which a sheet guide according to a preferred embodiment of the present invention is employed, and FIG. FIG. The feeding mechanism has the same structure as that described in connection with FIGS. 5 and 6, so the same members are denoted by the same reference numerals and detailed explanation will be omitted.

As shown in FIG. 1, between the feed roller 12 and the presser plate 20, a sheet guide 36 extending parallel to the feed roller 12 is rotatably supported on the main body 10 of the apparatus. This sheet guide 36 is
It is formed in a “L” shape in cross section, and its first
A plurality of ribs 36c are formed on opposing surfaces of the regulating piece 36a and the second regulating piece 36b at predetermined intervals in the longitudinal direction. Then, as shown in FIG. 2, through holes 40, 40 (only one is shown) of a required diameter are bored in the ribs 36c, 36c formed at both ends in the longitudinal direction. Through hole 4 is inserted from the outside of both side plates 10a, 10a.
It is rotatably supported via rivets 42 and 42 inserted through holes 0 and 40, respectively.

Further, as shown in FIG. 2, the first regulating piece 36a and the second regulating piece 36b of the sheet guide 36 have
A notch 38 (first regulating piece 36a
(Only the side shown) is formed. The open ends of the first regulating piece 36a and the second regulating piece 36b are arranged to face the feed roller 12 so that the O-ring 16 faces the corresponding notch 38. Thereby, adjacent notches 38, 38
The comb tooth portion 44 formed between the two is located inward from the outer circumferential surface of the O-ring 16. Therefore, the sheet material 14 fed by the feed roller 12 is guided to the surface side of the first regulating piece 36a facing the presser plate 20, as shown in FIG. 4a, and is guided to the cutting mechanism located below. (not shown).

Here, as shown in FIG.
The guide 36 is located close to the outer peripheral surface of the rivet 2 and is configured to prevent the guide 36 from rotating significantly around the rivet 42. That is, for example, when the sheet guide 36 rotates clockwise around the rivet 42, the comb teeth portion 44 of the first regulating piece 36a comes into contact with the feed roller 12, and the rotation of the guide 36 is prevented ( (See Figure 4a). Conversely, if the sheet guide 36 rotates counterclockwise,
The comb teeth portion 44 of the second regulating piece 36b is connected to the feed roller 12.
The guide 36 is prevented from rotating. Note that when the second regulating piece 36b comes into contact with the feed roller 12, the comb tooth portion 44 of the first regulating piece 36a
However, as shown in FIG. 4b, the O-ring 16 is set so as not to protrude outward from the outer peripheral surface of the O-ring 16 wound around the feed roller 12.

Effects of the Example Next, the effects of the sheet guide of the rolled wet towel manufacturing apparatus according to the example will be explained. First, when assembling the sheet guide 36 to the device main body 10,
The comb tooth portions 44, 44 of both regulating pieces 36a, 36b of the sheet guide 36 are positioned so as to be close to the outer peripheral surface of the feed roller 12 already arranged.
Next, the rivets 42, 42 are attached to the ribs 36c, 36c from the outside of the side plates 10a, 10a, respectively.
By inserting the sheet guide 36 into the through holes 40, 40, the sheet guide 36 is rotatably positioned at a fixed position. At this time, the comb tooth portion 44 of the first regulating piece 36a
is located inward from the outer peripheral surface of the O-ring 16 of the feed roller 12. In addition, the sheet guide 36
When assembling the sheet guide 3, the sheet guide 3
Since the positioning of 6 is done automatically, assembly can be easily performed.

Next, the sheet material 14 pulled out from a sheet roll (not shown) is inserted between the feed roller 12 and the presser plate 20, and then the rolled wet towel manufacturing apparatus is operated. The sheet material 14 pressed against the O-ring 16 by the presser plate 20 is sequentially drawn out from the sheet roll and fed as the feed roller 12 rotates.
At this time, the sheet material 14 that is fed while being in contact with the outer peripheral surface of the O-ring 16 is as shown in FIG. 4a.
The sheet is guided by the surface side of the first regulating piece 36a of the sheet guide 36 and is smoothly fed to the cutting mechanism.

The sheet material 14 fed to the cutting mechanism is cut in the width direction by the cutting mechanism, but at this time, a downward pulling force may be applied to the sheet material 14.
In this case, as shown in FIG. 4b, the first regulating piece 36a and the second regulating piece 36a in the sheet guide 36
The connecting portion with b is pressed by the sheet material 14, and the guide 36 is urged to rotate counterclockwise around the rivet 42. However, at this time, the comb teeth portion 44 of the second regulating piece 36b of the sheet guide 36 comes into contact with the circumferential surface of the feed roller 12, and the rotation of the guide 36 is prevented. Therefore, the comb tooth portion 4 of the first regulating piece 36a
4 does not protrude outward from the outer peripheral surface of the O-ring 16, and smooth feeding of the sheet material 14 can be achieved.

Effects of the Invention As explained above, according to the sheet guide of the rolled wet towel manufacturing apparatus according to the present invention, the feed roller By bringing the
The sheet guide can be positioned.
Therefore, there is no need to make fine positional adjustments within a narrow device, and the assembly work can be performed extremely easily. Furthermore, even if a force is applied to the sheet guide to rotate it, the sheet guide is prevented from rotating in either the forward or reverse direction by the first restriction piece and the second restriction piece. It is configured. Therefore, the end of the sheet guide can be prevented from protruding outward from the outer peripheral surface of the O-ring and the sheet material can be prevented from getting caught, and smooth feeding of the sheet material can always be achieved.
